Use of an intraoral scanner to evaluate orthodontic treatment for dental malocclusion in a dog.

In human dental practice, intraoral scanners (IOSs) are increasingly used to evaluate the oral cavity. However, there have been no reports concerning evaluation of the canine oral cavity using IOSs in veterinary dentistry. In this case, optical impressions obtained with an IOS were used for 3-D evaluation of the orthodontic treatment outcome. Additionally, few reports have addressed the optimal orthodontic force for canine teeth. Therefore, this case explored whether sufficient tooth movement into the extraction site could be achieved with a lighter orthodontic force than previously reported. An 8-month-old spayed female dog. A retained right maxillary third deciduous incisor (503) caused distoversion of the right maxillary third permanent incisor (103), leading to dental malocclusion that involved contact between 103 and the right mandibular canine teeth. All retained deciduous teeth were extracted. Mesial tipping movement of 103 into the extraction site of 503 was achieved with light orthodontic force using an elastomeric chain. An IOS was used to construct 3-D optical impression data from oral stone models taken before and after treatment, and tooth movement was evaluated. The results showed that 103 had sufficient tipping movement and no anchorage loss; comfortable occlusion was achieved. In addition to crown length extension, labioversion and mesioversion of maxillary incisors (other than 103) were observed. Detailed intraoral evaluation with optical impressions was beneficial in the orthodontic treatment of a dog. Light orthodontic force may be sufficient for movement into the extraction site.

Comparative evaluation of incidence of dentinal defects after root canal preparation using three different endodontic retreatment systems - An in vitro study.

Safe and efficient removal of all root filling materials from the root canal system without compromising radicular dentin structure is essential for optimal nonsurgical retreatment. The aim of this study was to evaluate and compare the incidence of dentinal defects caused during root canal filling removal using conventional, rotary, and reciprocating retreatment file systems. A detailed protocol explaining purpose and procedures of the study was submitted to the Institutional Ethics Committee and ethical clearance obtained. Sixty human maxillary permanent central incisors were collected and decoronated to 12-mm standardized length. The canals prepared up to a master apical file size F3 with Protaper hand files, obturated using AH plus sealer, examined under the stereomicroscope (×40 magnification): Group I: Control (n = 15), Group II: Conventional (n = 15), Group III: Protaper Universal Retreatment Files (n = 15), and Group IV: Reciproc Blue (n = 15). After instrumentation, teeth were sectioned at 3, 6, and 9 mm from the apex to evaluate the presence of dentinal defects under the stereomicroscope. Statistics were performed using the SPSS, version, 25 (SPSS Inc., Chicago, IL, USA). Initially, normality test was done using the Shapiro-Wilk test and data were not normally distributed followed by Kruskal-Wallis test. P < 0.05 is considered statistically significant. Maximum percentage increase in dentinal defects was observed in Protaper Universal Retreatment Files followed by Conventional method and Reciproc Blue. Significantly Reciproc Blue reduced the incidence of dentinal defects after root canal preparation.

Discoloration after revascularization using calcium phosphosilicate-based bioceramic versus mineral trioxide aggregate in necrotic immature permanent anterior teeth: A Randomized clinical trial.

The aim of the current study is to evaluate the effect of calcium phophosilicate-based bioceramic "Totalfill bioceramic putty" and white mineral trioxide aggregate (WMTA) as the coronal plug on discoloration after revascularization of necrotic immature permanent anterior teeth. This study was conducted on (48) necrotic young permanent central incisors in children ranging from 8 to 14 years old, that were randomly allocated to either Totalfill bioceramic (Group I = 24) or WMTA (Group II = 24) as the coronal plug. Two visits revascularization protocol was adopted in this study using 1.5% sodium hypochlorite, followed by 17% ethylenediaminetetraacetic acid, and ending with a saline flush as irrigation solution. The double antibiotic paste was used as intracanal medication. The blood clot was used as scaffold followed by the application of collagen membrane followed by coronal plud malterial. Finally, the access was sealed using resin composite restoration and composite restoration. Clinical assessment was conducted at 1, 3, 6, 9, and 12 months, while radiographic assessment was conducted at 6 and 12 months. Data were statistically analyzed using the Chi-squared test for intergroup comparisons and Cochran's Q test for intragroup comparison. Clinically, Group I exhibited a success rate of 100%, whereas Group II exhibited a success rate of 85.7%. Radiographically, both materials showed a 90.5% success rate. There was no statistically significant difference between both materials for all assessed clinical and radiographic parameters at different follow-up periods. Both Totalfill bioceramic putty and WMTA can be used successfully as coronal plug in esthetic areas.

Correlation between Cleft Width and Adjacent Teeth Inclination in Patients with Unilateral Cleft Lip and Palate Using CBCT: A Retrospective Study.

To evaluate buccolingual and mesiodistal inclination of cleft-adjacent maxillary permanent central incisors (U1) and canines (U3) in patients with unilateral cleft lip and palate (UCLP) in the late mixed dentition and to investigate the correlation between the alveolar cleft width and cleft-adjacent teeth inclination using cone beam computed tomography (CBCT). Observational cross-sectional retrospective study. Department of Orthodontics, Hama University Dental School. 32 patients with UCLP (22 boys, 10 girls; mean age = 10.53 ± 1.51 years). Buccolingual and mesiodistal inclination of maxillary central incisors and canines were measured on both sides. Then, the cleft and non-cleft sides were compared using the Wilcoxon signed-rank test. Pearson's correlation was used to explore the association between the alveolar cleft width and cleft-adjacent U1 and U3 buccolingual and mesiodistal inclination. The cleft-adjacent central incisors were significantly inclined lingually and distally compared with their non-cleft antimeres (P = .003, P < .001, respectively). The cleft-adjacent canines were significantly inclined buccally and mesially compared with their non-cleft antimeres (P < .001, for both). A positive correlation was found between the buccolingual inclination of cleft-adjacent U1 and the alveolar cleft width (r = 0.49, P = .004). Patients with UCLP demonstrated a significant lingual and distal inclination of cleft-adjacent U1 and a significant buccal and mesial inclination of cleft-adjacent U3. The buccolingual inclination of cleft-adjacent U1 tends to increase with increasing the alveolar cleft width; however, the correlation was weak.

In-vivo evaluation of the effects of short-term dehydration and rehydration on the color differences of immature permanent incisor teeth.

It is aimed to evaluate the color changes of upper central incisor teeth with different root maturation levels after 15 min of dehydration and rehydration. Using the Cvek classification, 60 participants were divided into five groups. A spectrophotometer, equipped with a specially designed jig, was utilized for color measurements. Following isolation, color measurements were conducted at the dehydration process intervals of baseline, 1st, 2nd, 3rd, 5th, 7th, 10th, and 15th minutes. After mouth rinsing, measurements were repeated at the same time intervals during the rehydration process. CIEDE2000 (ΔE00) values and the Whiteness Index (WID) were obtained to compare the color changes between the initial readings and each interval. Friedman and Repeated Measures ANOVA were applied to compare classes by time during the dehydration and rehydration periods, as well as ANOVA and Kruskal-Wallis tests to compare by classes for each time (p < 0.05). Significant differences emerged in the mean ΔE00 values during dehydration and rehydration periods across all Cvek Classes (p < 0.05). While no statistically significant differences were observed among Classes at different minutes during the rehydration period (p > 0.05), it was particularly noted that the mean ΔE00 values of Classes 2, 3, and 5 at the 2nd minute of dehydration were statistically significantly higher than the mean of Class 1 (p < 0.05). However, when evaluating the starting and ending measurements of both dehydration and rehydration processes, and the overall change in ΔE00 and ΔWID, no significant variations were detected across the Classes (p > 0.05). In teeth that have just erupted and are still undergoing root development, dehydration in the initial minutes results in noticeable color changes. However, the change in ΔE00 and ΔWID of the teeth was found to be similar after the dehydration and rehydration processes. According to the Cvek classification, the lower color change in Class 1 teeth within the first 2 min of dehydration and the need for more than 15 min of rehydration for immature teeth with an open apex to return to their initial state after a 15-min dehydration are crucial for clinicians in terms of color assessment timing.

Developmental characteristics of the permanent upper lateral incisor in unilateral cleft lip and palate

ObjectivesThis study aims to provide insights into the developmental characteristics of the upper lateral incisor in individuals with unilateral clefts.Materials and methodsPanoramic radiographs of a consistent group of Caucasian children taken over time (ages 6, 9, and 12) were extensively reviewed. The study assessed the distribution pattern, eruption path, tooth development, and crown size of the upper lateral incisor within the cleft region.ResultsThe most commonly observed distribution pattern was the lateral incisor located distal to the cleft, accounting for 49.2% of cases. Furthermore, a significant delay in tooth development of the upper lateral incisor on the cleft side was noted at ages 6 and 9 (p > 0.001). Compared with the non-cleft side, these incisors often erupted along the alveolar cleft and exhibited microdontia (88.3%, p < 0.041).ConclusionLateral incisors on the cleft side display unique distribution patterns, microdontia, and delayed tooth development. Careful monitoring of the cuspid eruption is essential, as it can influence the eruption of the lateral incisor.Clinical relevanceA comprehensive understanding of the development of the upper lateral incisor relative to the cleft is vital for determining its prognosis over time. The position of the upper lateral incisor can also influence the timing and prognosis of secondary alveolar bone grafting. Preserving the upper lateral incisor favors arch length, perimeter, and symmetry in individuals with unilateral clefts.

Management options and long-term follow-ups for permanent double incisors: six to eleven-year case reports

BackgroundDouble teeth are dental anomalies that can lead to aesthetic and orthodontic problems.Case presentationThis report discusses two cases involving the multidisciplinary management of permanent maxillary left lateral incisors fused with a supernumerary tooth in two girls aged 9 and 10. Following intraoral and radiographic examinations, one was diagnosed with fusion, and the other was diagnosed with concrescence. The crown of the fused incisor was separated using a burs and extracted intraorally. The concrescent incisor was separated along its length using a laser and intentionally replanted extraorally. After a 6-year follow-up, no pathological signs were observed in the fused incisor. However, after an 11-year follow-up, external resorption was observed in the concrescent incisor.ConclusionsBoth incisors remained asymptomatic throughout the observation period. This case report highlights two different and effective methods employed to preserve the natural function, form, and aesthetics of double incisors.

Exploring Dens Invaginatus Types I and II: Diagnosis, Challenges, and Solutions - A Case Report

Dens invaginatus is a common malformation of maxillary lateral incisors with varying anatomical features that impose challenges to diagnosis and treatment. It is considered a real clinical entity which, even if the tooth is clinically healthy, it can cause pulpal damages that can progress silently and lead to necrosis and its complications. The aim of this article is to expose a clinical case of patient with two types of dental invaginations; I and II incidentally discovered during a routine radiological examination, affecting the two permanent maxillary lateral incisors which are clinically healthy, and which required endodontic treatment following pulpal damages. The focus will be on the description of the clinical and radiological characteristics of this abnormality, the difficulties and the strategies employed to manage this clinical condition.

Treatment Strategies for Incisors of Children Affected by Molar Incisor Hypomineralization: A Narrative Review

Today, molar incisor hypomineralization (MIH), which affects approximately one in seven children, is defined as a hypomineralized developmental enamel defect that often impacts at least one permanent first molar and frequently affects permanent incisors as well. Symptoms and signs include demarcated opacities of various colors, post-eruptive enamel deterioration, atypical caries and restorations, hypersensitivity, tooth loss due to MIH, and difficulty in achieving anesthesia. A detailed review of the scientific literature shows that there are many studies evaluating different treatment approaches for permanent first molars affected by MIH. On the other hand, there are very few scientific studies evaluating treatment approaches for affected incisors in patients with MIH. Most of these studies consist of case reports or series. White/creamy and/or yellow/brown demarcated opacities are commonly observed in affected incisors in patients with MIH. While these opacities increase the susceptibility of enamel to deterioration and dental caries, they also cause aesthetic problems and related psychosocial consequences. Treatment methods, such as resin infiltration, microabrasion, and/or dental bleaching, have been proposed for aesthetic and restorative purposes in affected incisors in patients with MIH. Additionally, various approaches to increase mineral content and relieve hypersensitivity have been recommended. The number of randomized controlled and prospective studies is quite low, but many case reports and case series have been encountered. The purpose of this review was to provide a comprehensive overview of the different treatment management modalities for permanent incisors affected by MIH. As a result, while resin infiltration, dental bleaching, microabrasion, and/or etch–bleach–seal techniques are preferred for aesthetic and restorative purposes in these teeth, it has been observed that agents containing casein phosphopeptide amorphous calcium phosphate, casein phosphopeptide amorphous calcium fluoride phosphate, fluoride, and calcium glycerophosphate increase the mineral content. Additionally, studies have reported that ozone and low-level laser therapy, in addition to these remineralizing agents, reduce hypersensitivity in these teeth. Although the findings of this review indicate that the level of evidence for current approaches is not high, clinicians may prefer one or more of the treatment approaches mentioned in this article based on experience and patient expectations.

Orthodontic Extrusion of Subgingivally Fractured Lateral Incisor and Canine Using Gold Post: A Case Report: 1 Year Follow-Up

ABSTRACT The case report describes a multidisciplinary approach using orthodontic forced eruption to facilitate prosthetic restoration of a maxillary permanent lateral incisor and canine with poor restorability for a young patient. Restoration after orthodontic eruption presents a more conservative treatment choice in young patients compared with prosthetic restoration after extraction. On examination, the patient had root stumps in the region of 22 and 23. We decided to treat the patient by orthodontic extrusion followed by endodontic post and core. The case was treated with the help of 19 gauge wire and gold posts.

A Minimally Invasive Esthetic Approach for Teeth with Molar Incisor Hypomineralization: a Clinical Case Report

Molar incisor hypomineralization (MIH) is a qualitative defect of enamel, clinically characterized by white or yellow/brownish demarcated opacities that affect permanent molars, often associated with permanent incisors. The etiology is multifactorial, including systemic and genetic/epigenetic factors. Defects of anterior teeth can negatively impact children since they might present lower self-esteem and socialization problems. Purpose: To describe a minimally invasive treatment for anterior teeth affected by molar incisor hypomineralization, performed with direct composite resin restoration and a universal adhesive system. Case Report: An 8-year-old patient sought dental care with complaints about her dental appearance, reporting suffering from school bullying. She presented a white-yellowish opacity on the maxillary right central incisor. After a clinical examination, she was diagnosed with molar incisor hypomineralization. To improve dental esthetics, a direct composite resin restoration was proposed. The enamel surface was prepared and etched with 35% phosphoric acid etchant solution for 15 seconds before applying the universal adhesive system. Two different shades of the composite were used for layering the material to disguise the defect without extensive removal of the dental structure. The result was satisfactory as it was possible to mask the opacity, reestablish enamel thickness, and improve the patient's quality of life. Conclusion: Conservative restorations comprising a universal adhesive system seem to bring desirable esthetic results for anterior teeth with molar incisor hypomineralization.

Agenesis of the maxillary permanent lateral incisors with the deciduous retained: Conservative and biomimetic approach using the BAIR technique.

Agenesis of the maxillary permanent lateral incisors is a condition that requires treatment aimed at improving the esthetics, even at an early age. However, traditional therapeutic protocols are long, invasive and have limitations and contraindications imposed by the age of the patient. Recent developments in restorative dentistry have provided a new approach to this clinical situation, in particular when the deciduous laterals are retained. We report two cases regarding the management of missing lateral incisors using Biologically Active Intrasulcular Restoration (BAIR) technique. The BAIR technique allows us to transform the shape of the deciduous lateral incisor into the permanent, acting both on the dental morphology and proportions, and on the appearance of the soft tissues and the gingival parables. The BAIR technique is a valid approach to cases of agenesis of the maxillary permanent lateral incisors, when the deciduous are retained. It does not require any preparation of the dental tissues, is reversible and minimally invasive. It is applicable to patients of all ages, and results are obtained in a single appointment. The BAIR technique allows a biomimetic conservative approach for the rehabilitation of congenitally missing permanent lateral incisors, when the deciduous are retained. It is a non-invasive protocol and effective in successfully restoring esthetics.

Management of permanent incisors affected by Molar-Incisor-Hypomineralisation (MIH) using resin infiltration: a pilot study.

To compare the aesthetic improvement of Molar-Incisor-Hypomineralisation (MIH) opacities treated by applying Icon-Etch for three cycles with the opacities treated by Icon-Etch for once, in the course of resin infiltration technique. Thirty incisors were sorted based on the colour of the opacities and then distributed according to the number of Icon-Etch cycles using a randomisation table into the groups: (1) White/Creamy one cycle, (2) White/Creamy three cycles, (3) Yellow/Brown one cycle, (4) Yellow/Brown three cycles. The primary outcomes of applying the resin infiltration to the opacities were compared amongst groups according to the parents' satisfaction, the amount of coverage, and the colour matching with the surrounding sound enamel. The stability of the results after 3months was evaluated using a spectrophotometer. The colour of the opacity pre-treatment affected the outcomes significantly (p < 0.05), compared according to the method of application (p > 0.05) in terms of parents' satisfaction. Whilst the multiple applications for Icon-Etch cycles showed more coverage amount in White/Creamy opacities than the application ones (p < 0.05); in colour matching, there was no statistically significant difference between the two methods (p > 0.05). For yellow/brown opacities, some negative results occurred with the single Icon-Etch cycle. In MIH opacities, it is possible to rely on the resin infiltration as a minimally invasive method to achieve acceptable results, especially with multiple Icon-Etch cycles applications in the white/creamy opacities. The colour stability has not been affected by either the colour of the opacity or the number of cycles.

Traumatic Dental Injuries Among 6 – 13 – Year - Old - School Children in Tikrit City

Background: An injury to both primary and permanent teeth and the supportingstructures is one of the most common dental problems seen in children. The extentof injury may vary from mild chipping of enamel to sever maxillofacial injury.The aim of this study was to find out the prevalence of traumatized anterior teethamong primary school children.Materials and methods: This study is a cross-sectional survey was carried outthrough clinical examination of anterior teeth among 720, 6-13 year old childrenenrolled in primary public schools of tikrit city. The prevalence of traumatizedanterior teeth was studied in relation to age, gender, type of injury in addition tothe cause of fracture. Recording and diagnosis of dental fracture were assessedaccording to Garcia-Godoy classification.Results: Males were more affected than females with odds ratio was 2.53 andstatistically was significant. The higher prevalence of dental trauma was recordedamong the age 10-11 year old. The permanent maxillary central incisors were themost frequent injured tooth and the most frequent type of fracture was the Class IIEnamel-Dentine, fracture without pulp exposure. Fall and playing were the mostfrequent causes of dental injury.Conclusion: data of the present study clearly show the need for dental healtheducation of children and their parents, so prevention programs are needed toimprove the dental health of Iraqi children.

Orthodontic management of midline diastema caused by mesiodens: A case series

Supernumerary teeth are teeth in excess of the normal number, found in both primary and permanent dentition. Mesiodens are the most common form of supernumerary teeth, usually found in the maxillary anterior region, in between the permanent central incisors. It may lead to complications such as malocclusion, unesthetic appearance, food lodgment, and cyst formation. Early diagnosis and immediate intervention are advised to avoid orthodontic and pathological complications. The case series here discusses three different cases for presence of supernumerary teeth leading to development of midline diastema. Extraction of the supernumerary teeth followed by fixed orthodontic treatment was performed to correct the malocclusion and improve the facial esthetics.

Comparative evaluation of fracture resistance of re-attached teeth using self-adhesive bioactive flowable composite after preconditioning the fractured coronal fragments with different remineralizing agents

One of the common forms of dental injury is anterior crown fractures, which mainly affects the teenagers and young adults. Fractures of the coronal portion of the permanent incisors characterize 18–22% of total traumatic injuries to dental hard tissues; of which 96% of them comprise the maxillary incisors. Uncomplicated fracture of crown is one of the most common types of dental traumatic injury. Dental trauma has an emotional impact on the patient’s overall health and can serious harm to the dentition. The treatment as well as prognosis of the fracture of coronal portion is a major challenge for a dentist because it has to accomplish various parameters like need to obtain an aesthetical result that approaches itself to its natural form and measurement, opaqueness and translucency of the original tooth structure in obtaining a effective restoration. It is suggested that reattachment of the fractured fragment is the best procedure for restoring an uncomplicated fracture of a crown, if a fragment is present. Reattachment of the fractured fragment offers major advantages over the conventional composite restoration. In reattachment, enhanced aesthetics is obtained because enamel’s true shape, colour, intensity, and surface texture are preserved. It re-establishes the major function and produces the favourable emotive and social response from the side of the patient. The reattached fragments are susceptible to further fracture when the restored teeth undergo further trauma. The resistance of the fractured teeth that has been reattached is the subject of the majority of concerns. Preconditioning the fractured fragments with remineralizing agents may aid in hydration. Thus, study will be conducted to evaluate the resistance of the fracture of a tooth that is reattached and pre-treated with remineralizing agents such as sodium fluoride and casein phosphopeptide-amorphous calcium phosphate and further reattached using one of the self-adhesive bioactive composite.

Interceptive Management of Dilacerated Maxillary Incisor: A Case Report

Because of the intimate physical link between the primary tooth and the permanent tooth germ, traumatic dental injuries in the primary dentition might impair the development of permanent teeth, particularly in the maxillary front region. Dilaceration is a condition that is commonly encountered as a result of dental trauma and is defined as an abrupt deviation along the long axis of the tooth that can be visible between the crown, root, or both. Due to their location within the esthetic zone, such teeth present a special difficulty to the pediatric dentist. This article aims to describe a case of a 09-year-old female patient with an ectopic permanent maxillary central incisor, which was diagnosed as dilacerated after the radiographic examination. The case was managed with an interceptive approach using a Hawley palate.

Enamel Hypoplasia among Tikrit City School Children Aged 6 Years to 13 Years Old

Enamel hypoplasia: its deficiency could be occurring when the enamel of the tooth does not form completely; this is may be due to many diseases or malnutrition. Enamel hypoplasia could be appear as horizontal lines or chain of grooves or pits over the outer surface of the tooth. The purpose of this current study was to find out the prevalence of enamel hypoplasia for the permanent and deciduous teeth in primary school children in Tikrit city, because children with enamel hypoplasia can suffer from cosmetic issues, tooth sensitivity and increased risk of dental caries. This current study is cross-sectional study was conducted through a clinical examination of teeth among 720 children of age rang (6 to 13) years enrolled in primary public schools of Tikrit city; they were accepted to participate in study after the aim of study was explained. The prevalence of enamel hypoplasia was studied in relation to age and gender. Diagnosis of enamel hypoplasia takes place by well trained dentist. The prevalence of enamel hypoplasia was founded to (6.2%); boys more affected than girls with odds ratio 1.03 and there was no statistically significant differences. The anterior teeth were the most affected teeth with enamel hypoplasia specially the upper permanent central incisor (2.9%). Developmental enamel hypoplasia has a high level of importance because of being predictors of dental caries. Children suffered from enamel hypoplasia require a preventive intervention as a priority and early treatment.

AGE ESTIMATION OF PERMANENT TEETH AND ITS CORRELATION AMONG LOCAL POPULATION

Aims and Objectives: The aim of this study was to establish the relationship between the ages of the eruption of permanent teeth in correlation with the local population and related factors. Methods: The present prospective observation study was conducted on one thousand students in schools and colleges aged 6–25 years by the Department of Forensic Medicine and Toxicology, Government Medical College, Amritsar. The data collected from this study were organized by presenting it in appropriate tables and graphs, which are statistically analyzed for percent ages and inferences. Results: The first permanent tooth to erupt is the first permanent Molar, which erupts at 75.9–77.9 months; permanent central incisor is the second permanent tooth to erupt following the first Molar. The age of eruption is 80.8–84.0 months. Permanent Lateral Incisor erupts at the age of 105.2– 107.4 months, and permanent Premolar one teeth erupt at the age of 109.5–112.6 months, permanent premolar two teeth erupt at the age of 131.0– 133.8 months, permanent Canine teeth erupt at the age of 142.6–144.8 months. Conclusion: It is thus concluded, based on the present study that the growth and eruption of teeth depend on various factors, including genetic as well as ecological aspects. The most accurate method, which depends on the conditions as well circumstances of each case, namely, the elements can be age, people participating in the study, supporting networks, availability of tools of age estimation, culture, religion, and ethnicity of the individual.

Kvaal’s dental age estimation method applied to Brazilian adults—a cross-sectional test of validity

BackgroundDental age estimation of adults is a challenging procedure in forensic odontology. Radiographic techniques have enabled non-invasive age estimation of adults since the 90’s. Kvaal’s method based on the deposition of secondary dentin has demonstrated broad applicability in several populations. Population-specific studies with this method, however, are scarce in South America. This study tested the validity of Kvaal’s method in a sample of radiographs of Brazilian adults. The sample consisted of 192 periapical radiographs of 106 females (55.2%) and 86 males (44.8%) with ages between 20 and 80 years old. The permanent maxillary right (n = 84, 43.8%) and left (n = 108, 56.2%) central incisors were assessed based on Kvaal’s method.ResultsLin’s coefficient of concordance between estimated (EA) and chronological (CA) ages was 0.800 (IC95% = 0.753; 0.847) (p < 0.001). The mean difference between EA and CA was − 2.84 years (p < 0.001). For females and males, separately, the mean differences between EA and CA were − 3.82 years (CI95% = − 5.38; − 2.25) (p < 0.001) and − 1.86 years (CI95% = − 3.56; − 0.17) (p = 0.031), respectively. Underestimations were predominant and increased with time.ConclusionAfter 28 years of the original publication, Kvaal’s method remains reliable for non-invasive dental age estimation of adults, especially for the analysis of the permanent maxillary central incisors of Brazilian individuals.
